The following are a few simple stomach exercises that can help you get those flat abs you have always dreamed of. It will also help you develop a strong core.

Leg Raises

Get Rock Hard Abs!

Leg raises place primary stress on the lower half of the rectus abdominis although the muscle fibers of the upper rectus abdominia are recruited as well. Secondary stress is also placed on the intercostal muscles. Because this movement works the hard to work lower abs you want to do this exercise before crunches.

Lie on your back on an inclined ab board with your head toward the raised end.

Grasp the end of upper bench with your hands to stabilize your body.

Bend your leg 15-20 degrees or until you feel your back relax.

Use your abdominal muscles to raise your feet in an arc to a position directly above your head.

Drop your feet in a return arc until they clear the bench.

Repeat until failure (get 15-25 reps).

Reverse Crunches

Reverse Crunches are a great exercise for working the lower abs.

Lie flat on your back with legs extended.

Raise your legs into an L position with your abs. You can flex your knees a bit.

Lower them to almost floor level and raise again.

Keep going until failure.

Bicycle Crunch

Targets: Upper Abdominals, Obliques, And Hip Flexors.

Lie back with legs straight and arms extended above head next to ears.

Roll up Crunch

Targets: Rectus abdominis (the "six-pack" muscle). 30 percent more effective than the standard crunch because the move challenges your abs through a fuller range of motion, recruiting more muscle fibers.

Lie back with legs straight and arms extended above head next to ears.
